Like references designate corresponding parts in the severaligures of the drawings.

of this application is designed to be made in varying lengths according to the length of hose A'to/be manufactured therein, and in'- cludes in its organization a plurality of upright ,skeletonframe stands 1 arranged 1n 'suitable spaced parallel relation and bolted or otherwise secured to an appropriate base. ln the embodiment ot the invention shown in the drawings, this base preferably comprises o posite parallel longitudinally arranged liase sills 2 consisting of :rl-beams upon which the frame stands are mounted.

.Each of the upright frame stands 1 has mounted on the top edge thereof, an upstanding bearing block carrying a series of anti-friction bearing rollers, 'or' equivalentbearings 4 arranged on the are of a circle and providing bearing supports for a pair of horizontal rotating bed rolls 5 5. These bed rolls 5-5 extend longitudinally throughout the entire length of the machine and are arranged in the same horizontal plane in side by side relation so `as toA provide thereon a rolling Working support for the hose which is carried upon its mandrel in the position 3 of the drawings.

.The horizontal bed rolls 5-5 have a bearing upon the anti-friction bearings 4 of the entire series oi frame stands or supports 1, thus insuring a uniform bracing support for the said` rolls throughout the machine, and

-consequently admitting oF rolls of any length being embodied in the machine structure. fin" addition to these intermediate supports d, for the said rolls 5, the spindle other position of the lifting cam associated The machine forming the subject matter indicated by the dotted lines, as at h in Fig.A

are mounted in extremities of the latter 6 arranged on the lsuitable terminal bearings terminal stands 1 of the machine frame, and

lt will, ot course, be understood that any oi" gifarinff may be em )lo Ted Afor drivinfT the I? o 1 t .I .D roiis o but tne arrangement descrioed is the preferable one, and, as shown in the drawings, involves the feature of having the gear 7 i'or one of the rolls arranged at one end of the machine and meshing with the pinion 8 at that end, while the gear 7 for the other roll 5 is located at the opposite end of the machine and ieshes with the pinion 9, the latter gear element being driven in connection with a driving gear clutch to be hereinafter more l'iarticularly referred to.

Cooperating with the pair of bed rolls 5, in the usual manner, is a top holding roll 11, The roll 11 may or may not be positively driven, but for purposes of the present invention is shown as an idle roll arranged longitudinally ol' the machine, parallel with the bed rolls, and lyiiig in a vertical 'plane between the vertical planes of said bed rolls, that is, the top roll lies above the contact Joint of the tivo bed rolls. The idle top holding roll 11 is preferably supported for loose rotary movement withinroller bearing yokes 12, of C forni and suspended by means of yoke stems 13 from the front ends 14 of vertically swinging hanger arms 15 carried by a hanger shaft 16 journaled in alincd bearings at the upper ends -of upright bearing brackets 17 arising from the rear upper corners o1" the frame stands l. Usually, in constructing the machine, the number of .roller bearing yokes 12 for hanging the top nun'iber of frame roll 11. correspond to the stands 1, and hence to the number of bearing and in order to supports forthe *bed rolls 5,

hold the roll 11 normally lowered under yielding pressure upon the hose body being operated upon, suitable pressure means are preferably employed, suoli as the pressure weights 18 carried upon angle weight arms 1f) rigidly carried by the hanger shaft 16 and pendent therefrom, as may be best seen from Fig. 8 of the drawings.

The raising of the top roll 11 is preferably el"ected through thc medium of a plurality of pull rod connections 2() with the rock arms 21 fitted to and projecting to the rear of the shaft 16, any desired number of the connections 2() 21. being employed according to the Each pull rod 2() carries at its lower end a clearance yoke 22 having a play over the top roll operating pinioiis 8 and 9 carried 5 by the main drive sliai't 10 upon opposite end `portions of said shaft.

suitable arrangement shaft 23 journaled insuitable leari ranged at the back edges of Vthe fra ne s The lower extremity ries an abutment roller i operates a rotating liftingr cam 26 fitted to l and turning with the said top roll operating l shaft 22S, and this latter shaft 'derives its ino- 1 tion from an intermittent .spur gear 17 i'itted l 23 and meshing with the drh en 28 of an intermittent controll ling clutch 2t) to be presently described. l The pinion 28 is one-half the diameter of the 2 spur gear 27 and hence the lat ter only makes l to said shaft clutch pinion a half revolution to one i'e.'olution of the pinion 28, and the said clutch a counter' drive shaft Si) ,iournaled in suitable bearings 3]A carried by cer iin' of the frame stands 1. The shaft 3() has mounted thereon a driven spur gear 82 meshing with a driving pinion i3 on the. main drive shaft 1t) heretofore referred has mounted thereon. the drive belt pulley 34, and a driving gear clutch which is designated in its entirety by the referencelnuniber \35. The driving gear clutch may be of any approved or standard construction of clutch and is therefore not specifically claimed or detailed herein, so for the purposes of the present invention it may be noted that the said cludcs in its organization a movable clutch member 36 having a feathered oi' equivalent connection with the main drive shaft 1() and adapted to be shifted into clutching and nnclutching relation with-respect to the noi'- nially loose member 37 (see. Fig. 2) of the clutch, which member 37 carries the roll driving pinion t) hcreinlrefore referred to, and which roll driving pinion'ineshes with. the gear wheel 7 fitted to one of tho bed rolls at one end of the machine.

The shifting of the movable clutch member 3o of the clutch 35 is accomplished through a shipper' device including a shipper lever 88 ivotally supported-at one end, as at 39, and liaving a yoke 4() connected with the movable clutch member 3o. The lever JSS-is normally drawn in one direct-ion by a retractilc clutch closing spring 41, and opposite its pivoted end carries an operatingarin 42 equipped at its extremity with acontact roller 48 held in operative engagement with a cani member 44 projecting from, orcarried by, the intermittent spur gear 27 and provided with a uniform dwell surface 45 throughout vpractically the entire periphery, but interrupted at a single point byca dropolfr recess L'lo for the roller end of the operating arm 42.

Referring to the intermittent controlling clutch 2t) arranged on the counter drive shaft 2U is carried bv to, and this drive shaft` drivingl gear clutch 35 in-V aangaan:

otherwise secured'astto the shaft 3() and is provided at one side with a circular ratchet provided at one end with a cover llange 56 for the ratchet Aface 49 ofthe disk 48,' and at vits opposite end has keyed or otherwise suitably secured thereto the clutch pinion 28 hereinhefore referred to. The loose sleeve member 47 ofthe clutch 29 also is provided thereon at one side of the flange 56 with a smooth annular riding surface 57 for the Wedge shaped cam piece v58 of a-clutch control lever 59 which is pivotally hung at one end, asat 60, on the top roll operating shaft 23, and the other end of'which has a pull rod connection 61 with one of the rocker arms 620i a foot treadle 63 which is carried upon a plurality of said rocker arms 62 mounted upon a rocking treadle shaft 65, to which shaft is conl nected overbalanee litt weights', or equivalentl means for normally holding the cam pieceY 58 of the lever 59 against the clutch member 47 and in operative relation to the inclined or wedged tappet lug 67 which is carried by, and projects from, an intermediate part of the clutch pin 51.

With this relation of parts, the rotation ofthe clutch 29, when engaged, carries the lug 67 against and over the wedge piece 58 with the resultof re t1-acting the clutch 'the clutch.

The frame oi' the machine is e uipped with. A asuitable feed table 68 supporte on brackets 69 at the front side of the machine. This table is arranged substantially in the horizontal plane ol' the tops of the bed rolls 5 and 'is utilized for feeding the wrappings to the hose body which is rotated between' the sets of ro1ls5-5',and 11.

Referring more particularly'to the action` oi' the4 machine andthe controlling mechanism, it may be assumed that the treadle is held normally elevated with the control cam 43 and 44 operate to disengage the said@ drivingv gear clutch 3tlg-Now, when the treadle is pressed down, the clutch control lever 59 is lowered out of engagement with thegtappet lug 67, thus permitting the spring pin 51 and disengaging 53 to come into' playA and automatically engage the clutch 29 with the result of the clutch pinion 28y commencing to rotate and transmit itsmotion to the intermittent spur gear 27,. This gear in turn causes its cam projection 44 to press the arm 42 of the shipper device outward and thereby disengaging the driving gear clutch 35 and consequentlyo stopping the rotation of the bed rolls 5-5. At the same time, the top roll 11 is automatically raised by the action of the lifting cams26 against the abutments 25 of the pull rods 2.0. When the driving clutch 29 has made one revolution, the tapl pet lug 67 automaticallypasses over the cam piece 58. oi' the control lever 59 and disengages the clutch 29. This occurs when the intermittent spur gear 27 has completed a hall' revolution, which is suiiieient to completely lift the top roll 11 and bring the liftmg means to the position shown in detail Fig. 8 of the drawings; The same action takes place to provide for lowering the top roll 11 and starting the movement of the bed rolls 5--5.

1n connection with the starting operation, it should be noted that While the top roll is lowering into its operative position, the two bed rolls are not running, but immediately upon the top roll reaching its operative relation to the bed rolls, the said bed rolls automatically start. This is caused by the relative arrangement of the cams 26 with relation rto the drop-oil recess 46 of the cam projection 44 of the gear 47. That is, when said cams are in the position shown in Fig. 8With the top roll elevated, the contact end or' the shipper operating arm 42 is on the hih side 45 of the cam 44, thus holding the ro l driving gear clutch 35 disengaged. Now, assuming the parts to be in the position shown in Fig. 8, when the treadle is depressed to disengage the lever 59 from' the intermittent clutch, the latter clutch becomes engaged and motion is transmitted Afrom the pinion 28 to the gear 27 with the-result of turning the said gear 27 one-hali` revolution.

raise and lower the top roll .11, it is simply necessary for the operator to depress the treadle 63to permit the intermittent clutch to become engagedgnnrhthen immediately remoye'the pressure from the treadle to permit the. control lever to fly back to operative position. y

Various changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacriiicing any of the advantages of the Y invention.
